There is some odd stuff in there:

but your event counts are consistent. It looks like corruption on 2 disks :(
Exactly.
Or did you try some things?
We tried updating the superblocks. It did not help, there remains
corrupt data somehow:
[root@localhost ~]# mdadm --examine /dev/sdb1
/dev/sdb1:
[...]
Number Major Minor RaidDevice State
this -11221199 -1288577935 -1551230943 2035285809 faulty
active removed

[root@localhost ~]# mdadm --examine /dev/sdc1
/dev/sdc1:

this 1038288281 293191225 29538921 -2128142983 faulty

That seems exactly what mdadm barfs on:
[root@localhost ~]# mdadm -v --assemble --scan --config=/tmp/mdadm.conf --force
[...]
mdadm: no uptodate device for slot 1 of /dev/md0
mdadm: no uptodate device for slot 2 of /dev/md0
